Svelte CLI (sv)

When to use this skill

Use this skill when the user wants to:

• Create a new SvelteKit project (sv create)
• Add an integration to an existing project (sv add with official or community add-ons)
• Run type / compile / a11y diagnostics on a Svelte project (sv check)
• Migrate a codebase between Svelte / SvelteKit versions (sv migrate)
• Build, test, and publish a custom sv add-on
• Read or edit svelte.config.js / vite.config.js programmatically via sv-utils

Do not use this skill for general Svelte component API questions, routing conventions, or store/state management — those belong to the svelte / sveltekit skills.
